Smart Displacement type Level Transmitter

Model SLX

OVERVIEW

The SLX series is a complete line of highly accurate and reliable high-performance torque tube type displacement level transmitters for the measurement. The model SLX is able to calculate boundary sur-face levels, specific gravity as well as liquid level. These microprocessor-based instruments have two-way communication capabilities that makes possible communication with the communicator with a SLX data base. Tasks such as self-diagno-sis or range or zero/span adjustment can, thus, be performed remotely.

FEATURES

Economical replacement• The model SLX can be fitted with a existing

chamber and float making it an economic investment.

Wide selection of element material• Select from various kinds of materials for wet-

ted parts to best suit your individual application.• A wide range of allowable operating pressures

and specific gravities is available to choose from.

High performance and highly reliable• Specific gravity for the process fluid can be set

from the communicator.• The effect of transient temperature is minimal.

Easy to adjust and maintain• Remote setting of range, self-diagnosis, zero/

span adjustment can be made from the commu-nicator.

• Exact, dumping and zero/span adjustments can be made by just using a screwdriver without having to open the meter cover.

• An LCD display indicator makes it easier to monitor liquid level and output.

Compatible housing and parts• Field proven chamber and float• The transmitter housing is common use with

our differential pressure transmitter.• Highly resistant to vibration

APPLICATIONS• Reactor, distillation, drum, recovery level measurement• Boundary surface, specific gravity measurement• Cryogenic (-196 °C liquefied gas etc.) and high-temper-

ature (+ 400 °C) applications• High-vacuum (-101.3 kPa) and high-pressure (15 MPa)

applications

OPERATION PRINCIPLEOne side of the torque tube is fixed onto the torque tube housing with screw. And the other side of the torque tube is assembled with torque arm, which is supported at the knife-edge supporting point. When installing or using the level mea-surement, suspend the float on the edge of the torque arm, and then the torque tube will be twisted by the float's weight. Use the level measurement in this condition.

When process liquid level changes, buoyancy will generate on the float according to the “Principle of Archimedes”. (Dis-placement type float is heavy. Therefore, float displacement may not change the level despite of the liquid level change. In general, it is designed as to be “generated buoyancy of liquid level at 100 % < float mass”). The proportionally generated buoyancy to the level, converts into torque by torque arm/knife-edge which suspends the float, and to the torque tube. Torque tube functions as to enclose the process liquid and as torsion spring function, and converts torque into angle dis-placement. This angle displacement transfers through torque rod and coupling, and detected by the angle displacement sensor. Then, it will be converted into liquid level signal by A/D converter, and sent it to CPU.

In case the process liquid contacts with torque tube, the shearing module of the torque tube material will be changed by liquid temperature, and then changes the torsional spring constant, and generates the output shift. To compensate the out-put shift, which generates by liquid temperature, temperature around the torque tube is detected by the temperature sensor, converted into temperature signal by A/D converter and then sent to CPU.

These liquid level signal and temperature signal are computed by CPU, and become digital signal based on each config-ured range by the communicator. This computed value will be converted into 4 to 20 mA DC analog signal with D/A con-verter and will be output.

Moreover, model SLX is provided parameters to compensate the output shift which generates by liquid temperature. (Default parameters are set at shipment, can be set using the communicator later.)

Note) * When using SF440A. However, the standard material is SFVC2A, temperature will be “0 °C or higher”.

Attention in usage• Azbil Corporation's standard Displacement type level

transmitter measurement range is set equivalent to float length H. Therefore, it will be unsuitable when detecting the levels around 0 % or 100 % (at normal operation), or when continuous output of 4mA or less or 20 mA or more is needed.

• When conducting the actual liquid adjustment (filling adjustment) after installing the displacement type level transmitter at the job site, be sure to set the float bottom to zero point (reference point at 0 % liquid level). (Struc-turally, if the measurement fluid is not in contact with float, output will not change.)If other than the float bottom is set to zero point (refer-ence point at 0 % liquid level), it may cause the measure-ment dead-band at the measurement range of lower limit (or upper limit), or may cause output linearity error.

Note) Change of specific gravity range• It is necessary to define the specific gravity of the liquid to be

measured in order to manufacture the model SLX correctly. However, range change with the communicator will suffice for range setting change for the ranges listed below.

• The scope of range change by the communicator depends on the float size for medium specific gravity range (model SLX110) / or low specific gravity range (model SLX120).Also, note that there is a limitation on boundary surface mea-surement (hydrometer) specifications for the low specific grav-ity meter (model SLX120).

1. Medium specific gravity (model SLX110):1-1. For liquid level measurement specifications, range

change is possible within the ‘Specific Gravity Range’ as given in Table 8 below.

1-2. For an boundary surface measurement (hydrometer), range change is possible within the scope given in Figure 2 "Range of Specific gravity".

The parameters are as follows:• Boundary surface measurement: Δγ = γ3 - γ2, γ3 > γ2

Whereas: γ2: Specific gravity of upper layer liquidγ3: Specific gravity of lower layer liquid

• Hydrometer: Δγ = γ5 -γ4, γ5 >γ4Whereas: γ4: Upper limit of specific gravity measurement

γ5: Lower limit of specific gravity measurement2. Low specific gravity meter (model SLX120)

2-1. Range change of liquid level meter specification is allow-able within the “Range of Specific gravity”, as given in Figure 2.

2-2. Boundary surface measurement (hydrometer) specifica-tions have following limitations on range change:

• Input Δγ from the the communicator.• The result of specific gravity range change may fall outside

of SS specifications, thereby accuracy cannot be achieved. The accuracy of the meter after range change can be veri-fied by substituting specific gravity γ, with the differential specific gravity Δγ in the verification equation on page 12.
